Web Video Creation and Optimization Forum

I have about 20 screencasts I'm going to make that relate to how to navigate certain online public government databases.

The purpose of these videos is to show users how to easily navigate the sites, but the other purpose is to attract links from the .gov sites to my own site.

My idea right now is to have the video only hosted on my domain, so that if the .gov site links to the video they have to link to my page, thus my site receiving all the link equity.

I wanted to know the thoughts of others on this forum if that is the best way to go. I realize that by hosting the videos on my own site, I lose much of the viral marketing aspect that YouTube offers, but on the other hand the .gov websites could just copy and paste the source code from YouTube and I never get the link juice from them.

Any ideas about how to retain the link equity from the .gov sites, but also how to increase the viral spread of the videos would be appreciated.
